Abstract: Chickpea (Cicer arietinum) is among the most widely grown grain legumes, with the major growing area concentrated in the Indian subcontinent. The species is diploid (2n = 2x = 16) and is the only domesticated species in a genus, which includes over 40 annual and perennial species. The progenitor of the cultivated form is the annual species C. reticulatum, but both annual and perennial relatives have been considered as donors of useful genetic variation. Recent advances in genomic analysis have expanded the results of earlier cytogenetic research in the species, which established base information with respect to the karyotype (chromosome number, length, and morphology; and some limited descriptions based on banding) and an estimate of nuclear genome size. Chromosome behavior at meiosis has been characterized in a few Cicer species and some wide hybrids. To date, only a small number of DNA sequences have been chromosomally localized using in situ hybridization. No detailed cytogenetic map has been elaborated, and the level of knowledge regarding the long-range molecular chromosomal organization of the genome is rudimentary. A recently developed method for sorting chickpea chromosome using flow cytometry now offers a more effective means of exploring the genome.
